First off my build is 4.53.651.1. I did the update thru sprint and followed all the unrooting procedures on here and re-rooted. I tried using the existing pc36img file on it to bring back to stock and it says wrong bootloader and skips it.
The problem i am running into at this point is that my wallpaper will not change and after i had an alarm set that is now my ringtone. I cannot get anything to change. I need to see if someone has the img file of the new bootloader so i can just flash it and be done with it. I would bring it back to bone stock and go from there. does anyone have this file or does it even exist? thanks
Long story short....
I rooted using Motochopper (QBKING77 video) - no problems
I was then going to do the hotspot mod by placing the modified files into the root folder.
I went to the root folder of the phone and...
Changed system.jar to system.jar.bak
Changed system.odex to system.odex.bak
I accidently restarted my phone and now the phone won't boot up. It just hangs on the yellow page with "sprint" on it.
How can I fix it? Can I get back to the root folder somehow and delete the .bak?
easiest way would be to flash the stock rom at this point. grab the no-data .tar and odin.
indeed flashing the Phone back to stock via ODIN will basically fix any "soft brick" ( i have had to do it already once)
Ok, please I hope you can help. New to rooting, I rooted my s5, and was working fine for days, then I got the error and yellow triangle "system software not authorized by Verizon" I downloaded one md5 firmware I found and flashed it using odin, after was done had the same error though. I was on version 4.4.2. (don't know if that matters) I cannot find any other "stock" firmware online to try that are md5 that I can use with odin. I can find all these custom roms in zip format but don't know how to flash to odin when they are in the zip format and not tar or md5. Right now im just bricked and cant do anything and trying to learn how to fix all this.

You can not just flash a ROM to your phone like with older phones, due to the locked bootloader. You have to install Safestrap and install the ROM there. You will find all you need to do that along with a link to a Youtube video explaining it all here ==>

ok, I did just like the guide says and applied the tar file. it goes through the whole process but when it reboots it still says "secure fail:modem" in the left hand corner and "system software not authorized by Verizon wireless has been found on your phone please turn off and got to nearest wireless store for help". Im lost....
do I have to download and flash all those files? the nk2,n12, ne9, ncg??? what is the difference? hope someone can help...been working on this for hours and there doesn't seem to be a lot of information on my issue

Stick with my instructions to reset and the instructions to root. I have all the files and instructions you need for root linked in the how to root section in the OP.
I did it word for word, and after boot it still comes up to the system software not authorized by Verizon screen. Don't know how to proceed?
any help would be greatly appreciated because at this point im out 450 dollars.
Took it too Verizon and they said there is nothing they can do but give 178 dollar gift card...anyone here have any other ideas? Followed the rooting guide here, updates were turned off, don't know what went wrong

Did you re-partition using the pit file when trying to go back to stock? This doesn't make any sense. To the best of my knowledge, even tripping knox won't result in this ...
Yeah I did. Don't know what to do...I seem to be the only one that has had this issue. My question is, what did I do to wrong to make this happen? How do I prevent it when I get a new phone? It seemed to happen after tethering using x tether on xposed? Is there an issue with xtether ?
No there's no issue there. I run it and have Odined back to stock a couple of times and re-installed it.
Work backwards. Un-install all xposed modules. Un-install SuperSU, towel root and everything else you have added. Do a factory data reset and then try to Odin back to stock maybe? Take it all the way back to NGC
You don't use any kernel tars, just the full factory image tar
Hi. I'm just gonna say this first: I didn't know entirely what I was doing when beginning this operation. I was just trying to do something fun and new, and it didn't pan out. I fully acknowledge that I am an idiot.
Now, the story. I was attempting to root my LGV20 with this guide: https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500 .
I have read over this thread more times than countable and thought I was doing everything correctly. I got to the "STEP3.BAT" portion of the guide and long story short, my phone crashed during it and somehow got foobarred.
It *kinda* works (as in it will boot for around a minute) and then blue/black screen into a reboot.
Is there any way I can save this phone? Hard resets, going into software, more dumb computer stuff, anything. I don't *need* to get this phone working again but it would be really preferable.
Simultaneously I fully accept the responsibility in failing the operations. I know that somewhere I must have messed up. If no-one wants/ can help me, tell me so. Just means new phone time.
If any more detail on what happened is needed, tell me.
First off: that guide is ONLY for the H910 (AT&T) variant, so make sure with your model
and also, when you said a "blue or black screen" it also has very small writings too, right? If so, then you may have faced a kernel/bootloader panic
Technically your phone is *still* alive, and your best method is to start over again, assuming if you read the whole guide carefully then you have backed up your firmware and can still access download mode.
Flash your stock firmware back (or use the H915 firmware provided by the guide), wipe and setup your phone again, then root the phone again.
I also suggest replacing the TWRP recovery inside the provided Dirtysanta folder cuz that's what i did when i faced the kernel panic

Thanks so much. Freaked out over this for a good bit. Came back, did what you said and we're back at that step fully working. Life saver.
Now my first guess as to why step3 failed is that i didn't have the latest version of TWRP. How can I set that up?
Inside the root package folder you can see an .img file named twrp 3.0.2-1- us996.img
What i did was downloaded a later version
(not latest cuz my phone won't boot at the latest version for some reason), copied the name of the original twrp and renamed it, paste it to the folder, overwrite the old one, and try to root it again

Alright, i've done that now too. Thanks. Is there anything else i should/need to keep in mind to ensure failure is not going to happen? I want to make 100% sure I get everything right this time.

No i don't think there is more things to do, the guide you're following is pretty much straightforward already.
100% guarantee is always a stretch here in XDA. But if you're still facing problems you can ask for help on that guide's thread.

I really want to give up on this. This time I successfully made it through all Step 3, but I also noticed that my screen was kind of glitched and not rendering properly at that stage. After it rebooted, I unplugged my micro usb cable and it gave me an angry green warning message I will attach here.
If you/someone can tell me what to do with this message from here or instruct me on how to flash stock H910 10 q back onto the phone without doing TWRP (since i'm evidently incapable of installing it) I would be most appreciative.
Slightly better picture without anything cut off.

The screen glitching is normal, the green text after boot however is somehow not.
Sad to hear that it still didn't work, there something seems to be interrupting the process of rooting your phone. I dunno if it has something to do with ARB (anti rollback) preventing you to root
If you want to go back to your stock firmware that you backed up, you can:
-Carefully flash each file of your backed up firmware through adb and fastboot mode
-build a zip file of your firmware and flash through TWRP (since it didn't succeed tho)

Unfortunately i can't find any guides when it comes to flashing the back up.
I did read something back then on turning it into a zip file, but even if you can build one you still need TWRP, in which case you haven't successfully installed, so that's no option
Flashing the backup files requires specific commands, especially to the part on what partition should it be flashed to
When LGUP backs up your phone's firmware, you can see a vast number of files(i can't remember how were they named, I'll look up a reddit post about it)
The files where named based on what partition it came fom (H910_modemxx_COM12, H910_system_COM12 or something like that)
These are image files, what i did as far as i can remember was rename these files by adding an IMG extension for ADB to recognize
Flash them according to it's partition name:
"Fastboot flash system H910_system_COM12.img"
"Fastboot flash recovery H910_recovery_COM12.img'
Etc.
To go to fastboot, turn off your phone and hold the volume down button , then plug your phone to the PC.
But i really cannot guarantee this, because for all i know, in order to flash this you need fastboot, and to get fastboot you need to root your phone, because only the engineering bootloader has it (i'm sorry if it's wrong tho), and flashing these files to fastboot might be a bit dangerous because it will not verify the files, there may be chances that you might flash a corrupted file. so flashing via LGUP is the safest option so far if you don't know what you're doing
So I didn't happen to back up my scatter or boot.img files when I used fastboot to try and flash the TWRP for the onn 10 inch, I was assuming it would work, but now I'm stuck with no recovery, no fastboot, no system, won't boot up when you hold the power button.
The only method of recovery I have is through MTK preloader and spflash, but I don't have the correct factory images or scatter file required to reflash stock. I've been looking everywhere online and can't find the right recovery files or any guides on how to recover from this.
Any help/files/advice would be greatly appreciated!!
Two things, I got access to my old account after a password reset
and, I got my tab back up and running, as well as root & xposed + gravitybox
I'm working on a guide as we speak.
Also, I will be dumping my firmware and adding the 10001885 to the list of stock image dumps on the main onn thread.
Hope this helps if still needing it, scatter file for the 100011885 mt8168 , good luck not responsible for anything lol i still cant get mine to work, anklosburner

Hey, i've had that same issue but have since fixed it by flashing the rom to the 100011886. I used some of the posts here to flash both vbmeta.img and boot.img to gain root, with success https://drive.google.com/drive/folders/17LtLtjKg4JJU9EJdIXPsyNjen0H-ilMX?usp=sharing . i eventually went too far and currupted my rom and had a hard time finding the stock ROM. I found the stock ROM to the 100011886 and flashed that to fix the problem, now i run that as my system and it boots up just fine. https://www.mediafire.com/file/107jp6gwbiwq87q/MT8168_ONN_Gen2_100011886.zip/file
fastboot erase super
fastboot flash super super.img
Would you happen to have the preloader bin file for the MT8168? After digging around, you have helped me get closer to bringing my hard brick back to life.

[STOCK] Stock Backups/Images/OTAs
Since these tablets don't have an external online resource for downloading system updates, only a sketchy OTA app (com.adups.fota) I'm collecting a library of OTAs, as well as boot/recovery/system images. I have access to a 10.1 with keyboard...
forum.xda-developers.com
Any rom you come across has to be extracted in order to get any necessary files from it. The thread mentions using 7zip but I've personally had better results extracting using ZArchiver. Also, a workaround I've found very useful when dealing with extraction issues, is removing the extension from the file. If all else fails, you may need to erase the super partition and reflash THAT

Thanks for the response. I'm at the end of that thread currently trying to see what I can find to fix my issue. Aside from buying another one from Walmart and trying to see if I can pull everything from a vanilla tablet, I'm not sure if I'll ever find the exact files.

I wish I would have waited until I read this today instead of further messing with it yesterday. It looks like everything you have is what I need, but now I am battling trying to get the COM port to stay active when the device is plugged in. I'll tinker with it and see if I can get back to the state I had it in yesterday where it was staying connected.

Would you happen to know/remember all the settings you checked in SP Flash Tool (I assume you used that) when you flashed things to get it working? It seems that my PC is able to communicate with the device again, but I'm unsure of how to proceed next.
Have you installed all of the adb & mtk drivers? If so, you should be able to use adb to reboot into the boot loader then use fast boot to flash the super file

It's hard bricked at the moment unfortunately, so there's no appearance of life to it. Attached picture is the error I get. https://www.gizmoadvices.com/list-sp-flash-tool-error-codes-solution-fix/ appears show info about the error, but it's not something I know how to fix yet.
The only way I can get the tablet to make moves in device manager (which I assume is a sign that the PC can at least partially recognize/see the device) is to click on Download in SPFT, connect tablet to PC via USB cord, and then hold down power button, which led to the error. Errors in SPFT I've received so far are 0xC0060001 and 0xC0060003.
When the tablet is active in the device manager, I assume that the device is in a powered state. However, when the device is grayed out, I assume it's in a powered off state (see other pic). I've yet to find away to actually flash anything to it.
